[0050] The alliance chain verification node applies to EACA for the corresponding ECERT through an offline written request, such as figure 2 As shown, after obtaining the ECERT, apply for the corresponding RCERT to RACA through an offline written request, such as image 3 shown. Assume that the alliance chain has four nodes ABCD, each of which obtains the corresponding ECERT and RCERT through offline channels, and then ABCD establishes a P2P connection with each other, and at the same time verifies the legitimacy of the sent ECERT and RCERT, such as Figure 4 shown.
[0051] At this time, if there is a new non-verification node E that needs to join, node E will provide ECERT to the VP node to prove that it has permission to access the alliance chain, but cannot provide RCERT. At the same time, verification node A will provide ECERT to non-verification node E and RCERT to prove the identity of its verification node, such as Figure 5 shown.
